PLEASE I REALLY NEED HELP ITS MY LAST QUESTION
Gwen pays the entry fee and buys 10 tickets. It costs her a total of $30. Tristan pays the entry fee and buys 15 tickets. It costs him a total of $40. Keith pays the entry fee and buys 10 tickets. It costs him a total of $30. In this task,
Let X represent the entry fee and Y represent the cost of each ticket in dollars.
how much Gwen paid.
y = 10x + 30
how much Tristan paid.
y = 15x + 40
how much Keith paid.
y = 10x + 30
Which two equations could you use as a system to find the cost of the entry fee and the cost of each ticket? Why?
You could use Gwen and Keith’s equations because there the same equation.
PLEASE ANSWER THIS:
Did you use elimination or substitution? What was the entry fee, and how much did each ticket cost? (You would use substitution)
